Description
This lecture covers the phenomenon of intermodulation in the context of two-tone input signals, explaining how the third-order intercept point characterizes nonlinearity. Through examples and calculations, the instructor demonstrates the impact of intermodulation on signal quality in a Bluetooth receiver scenario. The lecture also delves into the effects of gain compression and cross modulation, showcasing how nonlinearity affects amplitude and phase modulation differently. Various types of LNAs are discussed, including resistive feedback and current reuse LNAs, highlighting their design principles and noise characteristics.
